PURPOSE: To improve appearance by mounting a cap for inspecting a space on the rear side of a ceiling from the inside of a room on the upper end of a standing part erected from an edge of an opening of the ceiling toward the space on the rear side of the ceiling and providing a lighting fixture on the indoor side surface of the cap. CONSTITUTION: Since a lighting fixture 31 and an inspection opening cap 30 are, provided in a box 80, there is no need to mount any other item than the box 80 to a ceiling 20, and hence the surface of the ceiling 20 becomes trim. Thus, the cost for the ceiling 20 excluding the area of the box 80 can be reduced by using common items and construction work at site can be performed easily. And the cap 30 is only put on a standing part 21 and in the case of inspection, it is merely required to lift the cap to slightly, laterally shift it, and hence inspection can be easily conducted even if the space on the rear side of the ceiling is narrow. Further since the lighting fixture 30 is attached to the cap 30, a predetermined distance can be provided from a louver 50 and hence light is properly dispersed in the room. As a result, the appearance of the ceiling can be improved and construction can be easily performed at low cost. |
